Applicationfiled February 10, 1922.` Serial No. 535,482.

To all whom t may crm-cent.l

- Be it known that l, DANinL (LMULVI- nim., a citizen of the United"Statesfand resident of Hannibal, county of Marion,-and

` State of Missouri, have 'invented certain ture which shall be as` .light as possible consistent with the requisite strength, and to provide improved means of securing the legs and wheel to the body'structure. A further object is to provide a novel form of vdisk wheel which shall be of rigid construction and hence particularly adapted for use with a wheel barrow of the type/here inaiter described, both being designed to withstand hard usage. i i

.An illustrative form of the invention is shown in the accompanyingdrawings, in which v Fig. 1 is a top plan view of the improved steel wheel barrow ;A

Figs. 2 and 3 are, respectively, side` and front viewsof the same; 4

Fig. 4v is a top plan View of the integral parts, the front and rear plates,tleg`s and wheel l having been removed Fig. 5 is a detail view showing a preferred means of attaching the hub of the wheel to thebody brackets: land Fig. 6 is a central vertical section of the disk wheel. y I

The wheelbarrow, designated generally by the reference numeral 10, is' constructed entirely ofsteel and is adapted fory transporting heavy material, such` as cement, sand, brick, and the liked It is therefore essentialrthat it-fconsist 0f the fewest num ber,` of` parts secured together "inthe" firmest mannerpossible. i 1

As shown in Figs. 1 and 4, the bottom 11, sides 12, 13, and handles 14, 15, are formed of one piece of sheet steel. For

this purpose an approximately rectangular sheet, of suitable gage, of the proper length and breadth, may be'/ employed. From. this sheet a 4large `central portion is stamped out at the rear, leaving suliicient material at the sides to form kthe rolled handles 14, ,15, and the connecting portions between the sides and handles. As shown, the lower or gripping portions 'of the handles are smooth, the seams 41, 41,

vbeing'formed at the sides (see `2), thus' `avoiding injury to the hands of thevuser,

A similar but somewhat smaller portion,

45, is stamped out of the front of the sheet to allow room for a wheel 16 to turn there in. ing the material upwardly along thelongir tudinal lines 20, 21, sufficient material being left between the sides and the wheel opening 45 to permit the attachment of a horizontal bracket 48 to the base 11, in which bracket the wheel 16 is journaled and whose forward portion is shown as extending around the front oflthe wheehforming a guard therefor. i

The sides 12, 13,' are formed byl bend-y lnclined front and rear plates'l 24, 25,

whose edges are' adapted to ity within the inclined sides 12, 13, Amay be `firmly secured thereto and to the bottom 11 bymeans' vof rivets passing throughside flanges 26`and bottom flanges 27. The outer'edges of the sides 12 and 13 are preferably hanged, as

at 30, 31, and straps 28, extending laterally from the upper edges of the front and rear plates, .maybe rolled over the flanged portions, thus providing an additional securing means (see Figs. 1 and 3).

For the purpose of Alightening Vthe, structure apertures 18, 18, preferably in fthe form of right triangles, may be stamped out ofthe material from` which the sides are formed, the hypothenuse of the triangle being just in front of the line `along which the plate 24 is to be secured. A flange 2Od may be turned inwardly along this` line and serves to more securely hold the' front plate in, position. A flange 19 may be turned inwardly along the verticaljleg of the tri`- angle to prevent the material "at the` eXd tremefront end ofthe sidesy from Abeing bent by any blow it may receive. l fNo flange is necessary "along the base of 'the'triangle on account of the bracing action of `the bracket 48. 1

Legs 32 and 33, preferably of channel bars bent to substantially V shape, may be lliy riveted to the rear plate-.25, as at 34;, and to the bottom 11,'as` at 35.V

The wheel 16, having a central hub 38, is shown as supported by means of a bolt in the horizontal bracket 40 and in ini chned bracket arms 36, 37, the latter being Y secured to the front plate 24. As shown in Fig. 5, the bolt, afterbeing positioned, is

prevented trom rotation by means of al washer plate 41, .which lies between the Aflanges of the channel member 40, one end of the plate being bent upwardly and inwardly about the head of the bolt A simi lar vdevice holds the nut in position.`

In Fig. Gfthere is illustrated a preferred form..V of wheel designed for maximum ,strength andirigidity. A disk 4t2 is shown asformed integral with the steel hub 38, steel plates 43 and ist being` secured thereto and spaced apart adjacent their perlpheries by means `of thimbles. )The pe- 1 ripheries oit the plates are preferably flanged outwardly, and a tire 4:7, ot slightly greater ldiameter than the plates, is then compresA 4sibly fitted thereover and may be welded thereto-with an acetylene torch. The tire may falso be rolled over .the endsv of the flanges to turtherprevent its removal.'
